Power supply power rating refers to the maximum power supplied by a power supply. Generally, this value is labeled on the power supply in watts (W). It is closely related to the configuration of the computer, and usually requires the purchase of a suitable power supply based on the hardware configuration of the computer. If you choose a power supply with too little power, the computer will crash or fail to boot; if you choose a power supply with too much power, it will waste electricity.
Specifically, the power supply rating is the maximum power that the power supply can stably supply under standard test conditions. This test condition includes factors such as power supply temperature, input voltage, and load current. The Watt value is used to express the size of the power supply, with higher numbers indicating a more powerful power supply. However, wattage is not the only criterion for determining whether a power supply is good or bad; factors such as the quality and efficiency of the power supply also need to be considered.
In practice, in addition to computers, other electronic products also need to consider the power rating of the power supply. For example, household goods, medical equipment, automotive electronic equipment. For these devices, in order to ensure that they work properly, you need to choose the right power supply in order to avoid the use of problems caused by insufficient or excessive power. At the same time, you also need to pay attention to the quality of the power supply, the safety factor and other factors to ensure that the power supply used meets the safety standards.
